Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 3 generators on 28 points:

(1,2)(3,4)(13,14,18,21,19,15,17,23)(16,24,25,20,26,28,27,22);(2,4)(5,6,7,10,8,9,11,12)(13,15,19,14)(16,22,26,20)(17,21,18,23)(24,27,28,25);(6,9)(10,12)(13,16,18,25,19,26,17,27)(14,20,21,28,15,22,23,24)
